CVE-2026-108063: Red Hat Enterprise Linux 10

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

A flaw was found in libhangul. When parsing Hanja dictionary files, the library fails to verify that an entry contains a valid value alongside its key. By providing a specially crafted dictionary file to an application that queries it, an attacker can trigger an unexpected application crash, resulting in a Denial of Service (DoS).
